A Chinese scientist aims to unlock the secrets of 2-D material
For more than a decade, Chinese physicist Zhang Yuanbo has been hunting for two-dimensional materials in our three-dimensional world.
Zhang, 39, is one of the early scientists who tried to extract and analyze graphene, a carbon allotrope in the form of an atomic scale.
Graphene is hundreds of times stronger than steel. Pioneering work on it earned a Nobel Prize and opened the door to a whole new world of physics research in 2-D materials.
“Scientists have since found more than 200 2-D materials,” says Zhang, who works at Fudan University in Shanghai. “The field is very active. Almost all the universities I know pursue some kind of research related to it.”
In a previous Nanowerk Spotlight (“Nanotechnology for neural interfaces“) we looked at the use of nanotechnologies in the field of brain-machine interfaces, their comprehensive design principle is to augment or restore one or more of the three interrelated biological complications that arise from neural impairment: sensory malfunction, loss of motor control, or disease-elicited intellectual changes.
Researchers from Finland and Taiwan have discovered how graphene, a single-atom-thin layer of carbon, can be forged into three-dimensional objects by using laser light. A striking illustration was provided when the researchers fabricated a pyramid with a height of 60 nm, which is about 200 times larger than the thickness of a graphene sheet. The pyramid was so small that it would easily fit on a single strand of hair. The research was supported by the Academy of Finland and the Ministry of Science and Technology of the Republic of China.
NASA got in touch with me. “Would I like to attend a briefing on a new graphene technology they had been working on?” The first thing I did was check up to make sure this was real. Yes it was the NASA Langley Research Center. So I joined a few others and listened attentively to what their scientists had to say about something they call holey graphene. Read on to find out more…
Dr Zina Cinker is doing something rather interesting in the world of graphene. She is the Executive Director of the National Graphene Association (NGA) based in Nashville, TN, USA. Read on to find out why this is important…
The China-based Tunghsu Optoelectronic Technology has announced a new series of graphene LED ‘super lights’ at the 2017 International Graphene Innovation Conference. The new lights reportedly use graphene for heat dissipation and conduction.
Haydale has announced the first commercial sales of its products to Everpower Sheng Tie (Xiamen) Graphene Technology (“Everpower”). The sales are for a range of Haydale’s Silicon Carbide Fibres and 3D PLA masterbatch mixed with Haydale’s functionalized Graphene Nano Platelets (“Additive Manufacturing PLA” or “AM PLA”) for immediate delivery.
Finding a simple and effective strategy to eliminate tumor metastatic lymph nodes is highly desired in clinical tumor treatment. Herein, we reported a Chinese traditional ink (Hu-ink)-based treatment for photothermal therapy (PTT) of tumor metastatic lymph nodes. By simple dilution, stable Chinese traditional ink dispersion was obtained, which presents excellent photothermal effect because of its high absorption in near-infrared (NIR) region. Meanwhile, as revealed by staining and photoacoustic imaging, Hu-ink could transfer to nearby lymph nodes after directly injected into the primary tumors. Under the guidance of dual-modality mapping, the metastatic sentinel lymph nodes could be subsequently eliminated by NIR irradiation. The good biocompatibility of Hu-ink has also been verified by a series of experiments. Therefore, the Hu-ink-based treatment exhibits great potential for PTT of tumor metastatic lymph nodes in future clinical practice.
